EJECTOR MEVCHANISIVI.

Application filed August 27, 1923. Serial 1\To.V 359,692

The invention relates to ejectonmechanisms and more particularly toejector mechanisms designed for use in the discharging of water fromsumps in cellars.

These ejector mechanisms depend for their operation upon the flow ofwater under pressure through the ejector and since thev pressure of thewater in the supplyk pipes to which the ejector mechanisms are connectedvaries in dierent localities,

inverting of the sieve inL its housing andl consequent passage throughthe ejector mechanism of the sedimentcollected by the sieve isprevented.

Vith these and other objects in. view, the invention resides in thenovel features of 1 construction and combinations and arrangements ofset forth.

In the drawings:

Figure 1 is a vertical central section partly in elevation through anejector mechanism embodying my invention;

Figure 2 is a top plan view thereof;

Figure 3 is a cross section on the line 3 3 of Figure 1. Y

1 is the base of the ejector mechanism having the hollow chamber 2mounted upon the legs 3 and provided with the sump water inlet openings4. 5y is the ejector having the fitting 6 provided with the internallythreaded nipple 7 for coupling with the externally threaded 'nipple 8upon the hollow body 4. The fitting is also provided with the axiallyaligned internally parts as more fully hereinafter threaded nipple 9 forcoupling with theA D. YODER, OF DETROIT, MICHGN, ASSGNOR TO PENBERTHYrIIBTJZCLOR COM ting. 15 is the water outlet pipe communieating withthedischarge end of the Ven'- turi tube .and mounted upon the pipe 16 whichsurrounds the Venturi tube and is coupled to the internallythreaded-nipple 17 of the ttin'g. Y

As thus far described, water under presi sure upon passing through thenozzle 13 and the Venturi tube 11 entrains water in the sump, in whichthe ejector mechanism. is located, and ejects the same through theVenturi tube and the water'outlet pipe 15. To prevent the sumpwaterfront-1 returning into the hollow body 4 upon stopping of the inletwater there is the control valve 18 which automatically seats upon thenipple 8 of the hollow body.

19 is thev valvemechanism mounted upon the upper end of the water inletpipe 10 for controlling the flow of inlet water through this pipe andthe ejector 5, this valve mechanism being adaptedl to be coupled to asupply pipe containing Water under pressure. 2O is a fioat slidablysleeved upon and guided by the water inlet pipe 10 andl actuated by thewater'in the sump, this float controlling the operation of the valvemechanism.

21 is the fittingv of the valve mechanism having the water inlet andoutlet passagef ways 21 and 212 respectively separated by the portedpartition 22. 23 is the valve adapted to seat upon the partition andclose rapid opening and closing of the valve, the latter'is of thepoppet type and so arranged that in either its closed vor its openposition the pressures upon its opposite sides Iare the port therein. Toprevent iuttering or unbalanced, thereby tendingy to hold the same inits adjusted position. As shown, the valve moves to closed positioninthe direction taken by the inlet water flowing through the fitting 21,Aso that when closed the. inlet water exerts a pressure upon its rearface tending to hold the valve closed. rlhe valve when movedto openposition oc-; cupies the recess 24 inthe wall of the fitting V21, and asa consequence the pressure of` the inlet water exerted upon the valve atthis time tends to hold the valve open. Therefore, with thisarrangement, Vthe float 20 must exert greater force to move the outerend oit this rock shaft has secured thereto the lever 30 which has atone side 0i the rock shaft the counter-balancing weight 3l and isconnected at the other side of the rock shaft to the link the lower' endot the latter being iivotally connected to the top of the iioat 2O bythe screw 33. rlhe link 32 has the longitudinally extending elongatedopening Se: through which the lever 30 extends, the upper end ot thisopening rotating the lever to close'the valve and the lower end rotatingthe lever to open the valve.

Since the pressure ot water in supply pipes to which my ejectormechanism is adapted to be coupled, varies in different localities, andsince the pressure ot the inlet water atects the operation ot theejector mechanism by varying the resistance oii'ered to opening andclosing the valve, l have provided means for taking Care ot'thisvariation in water pressures. rllhis is accomplished by varying theleverage exerted by thetloat 2O upon the lever 30. As shown the portionot the lever 3() which is engaged by the link 32 is curved and madeconcentric with the water inlet pipe l0 and this curved portion of thel-ver is provided with the spaced projections 30. rthe width ot theelongated opening ot the link is slightly greater than the diameter oithe curved portion of the lever'lO, and as a consequence, when the link32 is in operative position, its movement along the curved portion ofthe lever is limited by the projections 30. To change the position oitthe upper end ot the link relative tothe curved portion ot the lever,the lower end ot the link is disconnected from the float 20 by removingthe screw 33, ai'ter which the lower end is swung irpwardly so that thenormally upper end of its elongated opening` can pass over theprojections B0 and then moved longitudinally of the curved portion tothe desired point, after which the normally lower' end of the link Aisswung downwardly v and the float 20 is rotated about the water .inletpipe 10 until the lower end of the i,eiv,o9e i .l

engaging portion concentric with .the water' inlet pipe, the positionoit the upper end of the link 82 relative to the curved portion may bereadily varied to take care of the diii'erence in pressure ot the waterin the supply pipe to which my ejector mechanism `is coupled.

To collect sediment in the water entering my ejector mechanism, l haveprovided the one-piece housing 36 having an externally threaded nippleadapted to be coupled to the inlet end of the litting 2l and aninternally threaded nipple adapted to be coupled to the water supplypipe. rihis housing is provided with the transverse sieve 37 which ispermanently secured therein. lt it is desired to remove the sedimentcollected by the sieve, the sieve cannot be inverted in the housing, orthe housing cannot be inverted, thereby allowing the sediment to passthrough the ejector mechanism, but the housf ing must be removed andthen the sediment can be removed by owing water through the housing inthe opposite directionV from that taken by the water in passing throughthe housing when coupled to the ejector mechanism.

From the above description, it will be readily seen that l have providedan ejector mechanism which may be readily adjusted to take care ofdifferent pressures ot' water in pipes to which my ejector mechanism isadapted to be kcoupled so that substantially the same operation otejector mechanism is possible in each instance. It will also be seenthat l have provided a water inlet valve control mechanism in which theinlet water exerts a pressure upon one side only of the control valvewhen in either open or closed position so that fluttering of the valveis prevented. Also, the arrangement of valve and mechanism between thevalve and float is very simple and offers butv slight resistancel to themovement of the valve. Furthermore, it will be seenthat have made asimple provision for collecting sediment in the inlet water whichprevents inverting the sieve in its housing to remove the sedimenttherefrom. Y
